As one of the engineers that worked on developing the 7.3L, I can tell a little about the history of that valve. Terry W. was the turbo engineer. He had an old evap solenoid for a Chrysler lying around. The rest is history. It did take some tweaking of the PWM carrier frequency to get OK control. ...And that is the history. I know that people will tell me that I am all wrong. That is what the keyboard warriors do. They weren't there in 1991.
Would love to hear more just a ROOKIE HERE LIVE THE 7.3 new to it I’ve been driving one for about a year now and I have found a whole new respect for it
You really ought to make some videos on the design and engineering of the 7.3, there are a lot of diehard fans out there, and you would be memorializing the information for all to see, for years to come
Pshh... who wants to listen to some engineer that only helped develop one of the most reliable/beloved diesels of all time??🤔 A s**t ton of people, that's who!!😁 But seriously, I'm sure I'm not alone in saying that I would LOVE to pick your brain. What an outstanding job you & your associates did.
I just got my 2002 f350 PSD back from a reputable shop and now my Waste gate sputters like a machine gun going up and incline pulling a trailer. My gauge shows 24psi max under this load. It has a bully dog tune that came with my truck when I bought it in 2005 but I've never had any issues until now. They replaced my up pipes and had my turbo off as well I believe but I have not talked to the "technician" yet. I'm making a list of things for them to recheck when I have time to give up my truck. I have # 4 and # 8 injectors that may be weak but they come on strong in the heat here in Texas..( could this be part of my issue ?) This is the last time I will ever let someone else work on my truck. I've always done the wrenching in the past but I got soft this one time. Never again ! Thanks for your videos !
I had overboost code, turbo got hot and melted my wastegate wire, truck blows CRAP ton of white smoke when coming out of high revs or a stop from high revs. Can’t really notice the white smoke at idle or driving. Been looking so hard for soulution hopefully you can help. Now my trucks not making any boost, weak, and throwing these two codes P0237 - Turbo/Super Charger Boost Sensor A Circuit Low P1247 - Turbo Boost Pressure Low
Clint. I thought of you today. I drove my truck all the way to work (1hr through the hills with grades included) and I forgot to do two things since I worked on the truck yesterday. Tighten turbo bolt 1 and tighten turbo bolt 2. I noticed I had an oil leak when I arrived at work. My truck was perfectly to the top of the fuel line on the dipstick before I left for work. I’m just curious how accurately you can guess this question and I believe you can take the cake as THE #1 7.3 guy!!! How much oil that I lose on my way to work. Another important detail is both of the bolts were only started on the threads. I have never gone back and tighten them nor threaded them in all the way
Interesting info. I might put one back on mine just see if theres a difference when its functioning properly. Ive owned and several 7.3s and always thought everyone just threw that junk boost solenoid in the trash. Ive never noticed a difference when its removed. I get it though some like to keep factory components intact.
Just had a KC Stage 1 turbo put in, EBVP ped delete, up pipes etc. Have intake/exhaust, no tunes. Went on a trip soon after w trailer, got there and checked my CTS for codes and P1249 was one of them which said overboost. I did hit 24 lbs of boost a couple times and I think I experienced defueling. Wondering if I need that boost fooler valve or if that’s a bad idea to let more boost occur with transmission reliability. Looking forward to your video on that too. 👍🏻 Also had P1119, 0603, 0541, 0475. 0603 is just from disconnecting batteries. I did put in the RiffRaff EBVP plug to stop its code when I got home, P0475. Cleared all codes, none have come back. Truck is running smooth so I’m wondering if other codes besides overboost just occurred from the work being done, but I am watching it. I imagine if I go hit 24 lbs again it’ll throw that overboost code again. Thanks again for another valuable video!
I pretty much a have totally stock '02 7.3L. What is the typical amount of boost pressure I should expect to see? Accelerating from Stop? Cruising on the Highway? WOT?
What is the thing to the left of the wastegate control valve sensor? It has a brass knob and porcelain non conductive ring. It has a Ground wire leading to my driverside block and a hot leading to one of things that maybe run my glow plugs? I had to disconnect them to remove my engine harness and for the life of me i cant remember how they went back on. I did tape and number every other connectors but didnt think id be be taking these off at first and then forgot. I hooked them back how i thought and started a fire with it melting each wire loom. Im more of a mechanic when it comes to an old wrangler thats fool proof.
Kind of late to the party here, but could this issue possibly have some convinced its a transmission/torque converter issue due to the lag/lack of psi building? I was thinking that was my issue, especially when towing a trailer with skidsteer. I know the power isn't being generated. The oil build up on the actuator was a tell tale sign too.
I have this exact solenoid on my 7.3, it's making a buzzing sound when I turn the key to ignition. It won't let the truck start, I replaced it & it ran for a couple days, but now it's doing it all again. Any ideas on what could be causing this? I thought maybe it could be stuck or frozen but even after removing it, tapping on it & warming it up some it's still the same issue. The voltage going to it is good as well.
its not uncommon in the last 2 years to get bad parts Quality is way down of late so thats one issue the second which is rare the wire harness is grounding out ever so slightly some where from the computer to the sensor
Clint mine seems to buzz as well. Is that an indicator that its bad, or is it common for these valves to buzz perse? Thanks for your time.reading my question as well. @CUSTOMWORKS7.3PSD
Is there a video on the transmission speed sensor and the vehicle speed sensor on the rear differential? Both my speedometer and odometer stopped working at the same time. There was a jolt, like the trans hard shifted, I looked down and no speedo or odometer. I replaced the VSS on the rear diff and the sensor on the top of the transmission but still no luck 🤷♂️
This is hard with the limited info, possible issue, wire harness from trans or NSS // rubbed trough wire in the steering column // water in the GEM // PCM fault // The last last last back cluster // CEL may not be on but you can check for code with a good reader to rule out PCM fault /// wires sometimes can be checked by wiggle testing have someone watch the cluster and you go around wiggling wires harness and pulling back and fourth
@@CUSTOMWORKS7.3PSD I really appreciate your help, thank you so much. Nobody, including myself has been able to diagnose. If you know a good diesel mechanic in the So California Area let me know 👍🏻
After looking at this inside out this valve doesn't open waste gate it accually dumps boost back to the intake the wastegate is an adter thought when all else fail it will open
no one is really explaining operation very well. appears to me to be a normally open valve. normal operatione pressure on red hose goes out the green and into intake. if boost gets high pcm signals solenoid to close and pressure builds in red hose and opens wastegate valve to decrease exhaust flow thru turbo thereby decreasing output from turbo
riff raff / amazon / ebay.... best is riff raff they will get your truck info and match with exact replacement if amazon or ebay you best be sure your ordering the one you need there a multiple top of engine harness's
Does the truck need this connected I have my waste gate completely disconnected and I have the solenoid just plugged in with no horses attached. I run no wastegate for more boost i quest my question is if the truck sees this not connected could it defuel or go into a limp mode and does the transmission use this sensor for shifting
Please go out and hook this back up! There are people with engineering degree's that put that thing on there for a reason .First that turbo is designed to have a max rpm the gate opens so you don't blow up the impeller wheel turbo wheel suck that into your motor its done, Next your heating the crap out of the bearing and if its the stock unit with the sleeve its getting cooked, next under heavy acceleration and quick off the pedal you are causing a pressure indifference between incoming air and out going exhaust wrecking the turbo and potentially busting a piston, valve, push rod, or main rod JUST so you can have 4 more PSI of boost . Nothing wrong with a boost fooler not a real fan but its safer If you need more boost get a larger turbo that is designed to be a larger turbo and won't wonk out the motor or blow up by design.
I enjoy listening to you...extremely helpfull...Thank you...God Bless..

I like how this guys videos pop up with any 7.3 question I search on youtube.
Got rid of the tubes and stock WG years ago. Slapped a 15lb after market wastegate connected directly to the y-pipe. Runs like a champ.
Love the 7.3 vids brotha, keep em coming!
i just need the rubber elbows 🥴

P0237 - Turbo/Super Charger Boost Sensor A Circuit Low

Where can you buy the top of the engine wire harness?
Thank you for all the info!!
i can tell from the pictures which way to hookup the wastegate green and red hoses at the solenoid end; but does it matter?
another great video bud ! thank you

If you did it the way I show in my video less than a tea spoon
which video?
I drilled and safety wired my bolts. No problem since.
What are the ohms a person should expect to see out of the solenoid 49-50 with a pulse? or no pulse?
Great video! Thanks for explaining.

Jump on RiffRaff site they have 2 answers for this and yes it will happen again so get that boost controller
I pretty much a have totally stock '02 7.3L. What is the typical amount of boost pressure I should expect to see? Accelerating from Stop? Cruising on the Highway? WOT?
top max is usually 18 psi
Is there an o ring on these where is goes against the spider? I took mine off and now I can’t remember lol. And o ring fits
Great video, very informative.
There is no suction at all on the red n green hose.. any suggestions?
Why does my wastegate control valve rattle with the key on, but engine off?

Only buy an oem harness, absolutely do not buy an aftermarket

Really my 94 has no tubes on it should it it's a 94 powerstroke 5spd

I kind of like it myself.
